Step 1 - The Trunk Your palm tree drawing should start off the trunk. Get a good image to use as reference if you are not familiar with how this tree looks. The trunk is really simple, but notice that it is slightly curved which is different than other trees. At the top of the tree there are some spiky parts that you should add. Try to keep in mind that the trunk is circular, so when you're adding the 'spikes' at the top they should appear to point in all directions.
